4 (Ilaims. (Cl. 1857-69) This invention relates to pivotable-lowered windows and, more especially, to improvements in the side closures therefor.

Windows of the foregoing class are installable in porch enclosures or wall openings and are usually referred to as jalousies, consisting essentially of a pair of opposed jamb or mullion members between which is arranged a plurality of pivotable louvers or panels.

It is an object of the invention to provide a louvered window construction having positive and substantially continuous side closures for the panels thereof, readily and economically manufactured and conveniently installed.

Another object is to provide a side closure construction for openings of the character described which will be elficient in operation and simple in assembly.

Other advantages of the invention will be discernible from the description thereof hereinafter set forth.

According to the invention, there is combined with a frame having a pair of opposed jamb members and a plurality of pivotable louvers or panels arranged therebetween, a unique end frame structure adapted to form the terminal end portions of the panels; these end frames carry a Weatherstrip member pivotable therewith relative to the adjacent jambs and co-operatively associated with vertically spaced fixed Weatherstrip members formed along the inner edges of the front faces of the jambs, whereby when the panels are closed, a substantially continuous Weatherstrip is formed along the sides of the panels to provide a side closure therefor. These end frames, in one form of the invention, are pivotable against a filler or adapter member designed to support one form of the fixed Weatherstrip members upon either the usual metal jamb members or those forming the sides of pre-cast concrete frames. The invention is embodied in the panel structures exemplified in the accompanying drawings wherein the views are as follows, like reference numerals designating identical parts but analogous parts appearing on opposite sides of the frame being of opposite hand, as will be understood:

Fig. 11, a section on line 1111 of Fig. 8.

The pivotable-louvered window has the usual rectangular frame having a pair of opposed jambs 1, which may be braced across the top thereof by a suitable head structure 2, and across the bottom by a sill structure (not shown). The views shown in the drawings are illustrative of one side of the window, it being understood 2,708,015 Patented May 10, 1955 that the construction on the opposite side will be of opposite hand.

Arranged between the jambs is the usual plurality of pivotable louvers or panels 3 which may be made of glass or any suitable material conventional in the art. The panels are carried at their ends by end frames comprising a vertically disposed pivot bar 4 from the lower or inner marginal edge of which is projected a pair of inwardly directed flanges 5 and 6, adapted to form a groove for the reception of the end portions of the panels 3. The outer flange 5 may be hooked as at 7 to support the panel against outward slippage from the end frames and one of the flanges may have the inner end thereof slit to provide a tongue 8 (Fig. 6) which is bent to bear against the back face of the panel to secure its retention in the grooves.

The pivot bar 4 is fulcrumed to the adjacent jamb for pivotal movement in relation thereto about a screw fastening member 9 which may be threaded into the inner face of the jamb (Fig. 5). This screw fastening member likewise secures a bracket 10 interposed between the pivot bar and the jamb (Figs. 5 and 6), the bracket having a rearward out-turned flange 11 whereby to overlie the inner face of the jamb and form a filler piece between the pivot bar and the jamb to adapt the pivot bar thereto. This bracket supports an upright strip 12 extending along the front edge thereof and adapted to overlie the front face of the jamb along the inner edge thereof.

Forwardly thereof, the pivot bar has an outturned flange 13 along the outer or top edge thereof, which is adapted to overlie the front face of the jamb along its inner edge when the panel is in closed position (Fig. 2) and form a continuous strip with the strip 12 thereabove, thus providing a continuous side closure for the panel adjacent thereto.

The outer end of the flange 13 is projected beyond the adjacent end of the pivot bar to provide a lip 14 adapted to overlie the top end portion of a fixed Weatherstrip designated 12-A positioned below the flange 13 when the panel is in closed position, this latter strip being of identical design with the strip 12 thereabove. Thus, the fixed Weatherstrip members function along the upper portions of the panel side closures in co-operation with the pivotable weatherstrips 13 to form substantially continuous weatherstrips along each side of the panels, combining with the pivot bars 4 to provide a Weatherproof side closure for the window or porch opening. Further, by the construction hereinabove set forth, the panels may be pivotably connected to the adjacent jamb surfaces at any desired point along the endwise sides thereof so as to obtain any desired balance of the panels upon their pivot points; the extent of the fixed and pivotable weather- 'strip members may be proportioned according to the location of the pivot points in relation to these endwise edges, as will be understood.

The panels may be oscillated by the usual operating bar 15 (Fig. 3), which is rockably connected through pivot fastenings 15-A to a tail-piece 16 extending rearwardly from the pivot bars 4 (Fig. 7). The bar 15 may be actuated through suitable crank and rack or gear train assemblies (not shown) well known in the art and not here required to be described.

By virtue of the brackets 19 formed therewith, the fixed Weatherstrip members are readily attachable to the jamb members, functioning to adapt the end frames thereto. It will be understood that my construction is adaptable as well to porch jalousie structures as to windows, the jambs herein shown and described being the constructional equivalents to the posts, mullions and the like found in porch enclosures. The modified form of my invention shown in Figs. 8 to 11 is addressed to a jamb member having inwardly extending tab members formed integrally with the frontal faces to define fixed Weatherstrip members. The end frames may be formed of one piece with the panels carried thereby. This construction may be stamped, extruded or otherwise fabricated to provide a panel 17 having upturned ends forming pivot bars 4.

The pivot bar 4 has an out'turned flange 13' along the forward portion of the exterior edge thereof to form a pivotable Weatherstrip member adapted to engage a fixed Weatherstrip member 12' formed therebelow and defined by a tab which is inwardly extended from the frontal face 18 of the main frame, the top of which forms the head 19. A like tab is extended from the frontal face of the jamb above the flange 13 to provide an upper fixed Weatherstrip 12", against the bottom edge of which the flange 13' is adapted to abut whereby to effect, when the panel 17 is closed, a substantially continuous weatherstrip along the side closures of the panels.

The flange 13' is extended at the outer end thereof to provide an overhanging lip 14 which overlies the strip 12. The pivot bar 4' is provided, as in the form of the end frame hitherto described, with a tail-piece 16', op-

crable by a connecting bar (not shown) of like construction as the bar 15 hereinbefore described, to oscillate the end frames to impart pivotal movement to the panels 17. Thus, the tabs forming the fixed Weatherstrip members 12 and 12", projecting inwardly beyond the inner faces 28, of the jamb members, may be stamped in a single operation fabricating the jamb members.

The invention will thus be seen to provide a simple and efficient Weatherstrip assembly for windows or openings of the pivotable louver type, forming substantially weatherproof side closures therefor, and meeting, in general, the objectives of my invention hereinabove set forth.

Of course, the invention is susceptible of various modifications without departing from the scope thereof as recited in the appended claims.

I claim:
